Lubuntu 17.04 New Install Folder Allocations not Optimum

I have just installed KiCad on an old Dell laptop with Lubuntu 17.04.
Seems to work fine, but the folder allocations are not to my liking.
I have a launch icon in the standard Launch Window and several folders in my Home folder.

The optimum would be an Applications folder added to the Launch Window, containing KiCad, and a KiCad folder in the Home folder.

Is it possible to re-arrange folders ?
Should I remove KiCad, re-arrange my Lubuntu structures, then re-install KiCad into the desired folders ?
